Real Cittadella

Background and construction
The Real Cittadella was built by the Spanish Empire (who controlled the Kingdom of Sicily) between 1680 and 1686. It was built to defend the port of Messina, but it was also meant to establish a strong garrison in the city to prevent the population from revolting, as had happened a few years earlier in 1674.
The fort was designed by Carlos de Grunenbergh, the military engineer of the Viceroy of Sicily. It was built in the centre of the peninsula of San Raineri, and was cut off from the mainland by a moat. The extremity of the peninsula was occupied by the Forte del Santissimo Salvatore.
A neighborhood populated by 8000 people, a Benedictine monastery and several churches had to be demolished to make way for the construction of the Cittadella.

18th and 19th centuries
The Spanish lost control of Sicily to the House of Savoy in 1713. In 1718, they invaded the island during the War of the Quadruple Alliance, and the Cittadella surrendered to the Spanish general Spinola. A year later it was recaptured by the Austrian Count Claude Florimond de Mercy. The Cittadella was again captured by the Bourbon Charles III of Spain in 1735, during the War of the Polish Succession.
The fort was also used as a prison, and the French geologist Déodat Gratet de Dolomieu was imprisoned there in 1798.
During the Sicilian revolution of 1848, the rebels did not capture the Cittadella, although they succeeded in taking over Forte Gonzaga and a number of other fortifications in the city. The rebels bombarded the Cittadella, but Bourbon troops held out until a relief force arrived in September 1849 and crushed the rebellion.
The Cittadella was again heavily bombarded by the Piedmontese army during the Expedition of the Thousand in 1860. It was the last stronghold of the…

The Real Cittadella was a pentagonal star fort, and was typical example of 17th century military architecture. It had five corner bastions (named Norimberga, San Francesco, San Carlo, San Stefano and San Diego), which were linked by curtain walls. A cavalier was located on each bastion.
In addition, the fort had a number of outworks, including a ravelin, lunettes, counterguards and faussebrayes.
